以云南东部山区4种群落39个样方调查的205个物种数据为基础,分析群落谱系结构,以推断植被恢复过程中的群落构建机制。结果表明:(1)不同恢复方式所形成的华山松林、水冬瓜林以及次生常绿阔叶林均呈现谱系聚集格局,表现出生境过滤作用的主导性;(2)在处于森林恢复初期的火棘灌丛中,草本植物在大尺度上呈现随机格局,可能是生境过滤与竞争排斥双重作用的结果;(3)群落过去的状态或经历(如农耕、砍伐等)所形成的影响可能一直存在,从而使得恢复的群落谱系结构在生境过滤作用下更加趋向于聚集;(4)不同生活型植物的谱系结构具有差异,反映出植物群落构建的主导因素会因植物生活型不同而具有差异。
Based on the data of 205 species surveyed by 39 quadrats from 4 communities in the eastern mountainous area of Yunnan, the community phylogeography was analyzed to infer the community building mechanism during vegetation restoration. The results showed as follows: (1) The species diversity of Pinus armandii, Shrub-watermelon and secondary evergreen broad-leaved forest formed by different restoration ways showed the dominant pattern of habitat filtration; (2) During the early stage of forest restoration In the case of the pyracantha bush, the herbaceous plants present a random pattern on a large scale and may be the result of the double effect of habitat filtration and competitive exclusion. (3) The impact of the past status or experience of the community (such as farming, deforestation, etc.) may have been (4) There are differences in the pedigree structure of different living plants, which shows that the dominant factors of plant communities are different due to different plant life forms.
